Function: ImportTypeLib
loads a type library and returns a wrapper object
Parameters:
lib - either the path to the library or the GUID if it is registered within the system.
If the path passed points to a file (e.g. a DLL) containing the type library, but it is not the first resource, append the index like so:
> ImportTypeLib("C:\Path\to\Lib.dll\2")
[opt] version - if a GUID is passed, specify the type library version here. Defaults to "1.0" (use exactly that format!).
